First Lattice QCD Determination of Lepton-Flavor-Universality Ratios in Light-Meson Leptonic Decays

Peter Boyle, Norman H. Christ, Xu Feng +4

The ratio of electronic to muonic leptonic decay widths, $R_{e / μ}$ , for the light mesons $π$ and $K$ , provides a clean test of lepton flavor universality (LFU) and a sensitive prob…

Isospin-breaking effects in inclusive hadronic $τ$ data for the muon $(g - 2)$ from first principles

Mattia Bruno, Taku Izubuchi, Christoph Lehner +3

The knowledge of isospin-breaking effects in hadronic $τ$ decays is required for a high-precision determination of the Hadronic-Vacuum-Polarization contribution to $(g - 2)_{μ}$ from e…

Lattice Calculation of Light Meson Radiative Leptonic Decays

Peter Boyle, Norman H. Christ, Xu Feng +4

In this work, we perform a lattice QCD calculation of the branching ratios and the form factors of radiative leptonic decays $P \to ℓ ν_{ℓ} γ$ ( $P = π, K$ ) using $N_{f} = 2 + 1$ doma…

Lattice Calculation of Short-Range Contributions to Neutrinoless Double-Beta Decay $π^{-} \to π^{+} ee$ at Physical Pion Mass

Peter Boyle, Felix Erben, Xu Feng +7

Neutrinoless double-beta ( $0 ν β β$ ) decays provide an excellent probe for determining whether neutrinos are Dirac or Majorana fermions. The short-range matrix elements associated wit…

Lattice calculation of the $η_{c} η_{c}$ and $J / ψ J / ψ$ s-wave scattering length

Yu Meng, Chuan Liu, Xin-Yu Tuo +2

We calculate the s-wave scattering length in the $0^{+}$ sector of $η_{c} η_{c}$ and the $2^{+}$ sector of $J / ψ J / ψ$ using three $N_{f} = 2$ twisted mass gauge ensembles with the lattice spacing…

Long-distance Contributions to Neutrinoless Double Beta Decay $π^{-} \to π^{+} ee$

Xin-Yu Tuo, Xu Feng, Lu-Chang Jin

Neutrinoless double beta decay, if detected, would prove that neutrinos are Majorana fermions and provide the direct evidence for lepton number violation. If such decay would exist…
